你知道如何在 apache mina ssh 客户端执行 ctl+c 命令吗？我正在尝试这样做

session.executeRemoteCommand("\u0003", output, StandardCharsets.UTF_8);

但我收到命令不能为空的错误。命令以 mina 为单位进行修剪。你有什么想法？

java.lang.IllegalArgumentException: Command may not be null/empty

我找到了解决方案。https://javahowtos.com/guides/108-security/389-connect-to-ssh-server-with-java-using-apache-mina-sshd.html

使用 ClientChannel 我可以向 ssh 服务器发送 Ctrl+C 命令。
